A block of mass m = 30 kg is being pulled with forces F1 = 122 N and F2 = 103 N that are in opposite directions as shown in the figure below. If the block does not move in the presence of these forces, what is the magnitude of the static force of friction acting on the block? Express your answer in units of N using zero decimal places. You can take g = 9.80 m/s2 if necessary.

A block of mass m = 8, 3 kg slides on a rough surface and moves toward a spring with a spring constant k, as shown in the figure below. When the block is d = 20 m away from the spring, it has a velocity of v = 16, 7 m/s. When the block momentarily stops, it has compressed the spring by x = 34 cm. If the coefficient of kinetic friction between the block and the surface below is μk = 0, 32, determine the spring constant, k = ? Provide your answer zero decimal places. Take g = 9.80 m/s2.

Two blocks of masses mA = 7, 8 kg and mB = 16, 8 kg are placed on a frictionless horizantal surface. A massless spring spring is attached to the more massive block, and the two blocks are pushed together with the spring between them. A cord initially holding the blocks together (at rest) is cut and after that the blocks move in the opposite directions as shown in the figure below. What is the ratio of the speeds of the blocks after the cord is cut, vA/vB = ? Express your answer using one decimal place. Please note that the system consists of the two blocks and the spring and the net external force on the system is zero. a After b

A block of mass 8 kg is pushed against a wall by a stick that is oriented at and angle 66∘ with the horizontal direction and is being pulled by a vertical string at the same time. The block is moving along the wall with a constant downward velocity. There is kinetic friction between the block and the wall. Given that the normal force exerted by the stick on the block is 43 N and the tension on the block is 37 N. find the coefficient of kinetic friction between the wall and the block, μk, that allows the block to slide with constant velocity. Use g = 9.8 m/s2 and retain your answer to two decimal places.
